Journalists swarm into London for the Games

With less than two weeks to go before the Olympic Games, hordes of competitors are pouring into London from across the globe and limbering up - but they're not athletes.

Promising coverage on an unprecedented scale and record-breaking use of social media, the 21,000 journalists, photographers, cameramen and technicians will in fact be twice as numerous as the athletes they are covering.

The BBC, Britain's official Olympic broadcaster, will offer up 2,500 hours of live coverage and "more online and mobile services than ever before".
